“…Second, the selective modal analysis (SMA)-based model reduction method is applied to obtain a first-oder model [19], expressing In the time scale of dynamic frequency response, the most relevant modules in a WTG are the induction machine and its speed regulator, that is, the rotor-side converter (RSC) control. The dynamics of grid-side converter (GSC) are usually ten times faster than that of RSC current loop for stability reasons [20], and thus the GSC and corresponding controller can be omitted.…”

Grid supportive (GS) modes integrated within distributed energy resources (DERs) can improve the frequency response. However, synthesis of GS modes for guaranteed performance is challenging. Moreover, a tool is needed to handle sophisticated specifications from grid codes and protection relays. This paper proposes a model predictive control (MPC)-based mode synthesis methodology, which can accommodate the temporal logic specifications (TLSs). The TLSs allow richer descriptions of control specifications addressing both magnitude and time at the same time. The proposed controller will compute a series of Boolean control signals to synthesize the GS mode of DERs by solving the MPC problem under the normal condition, where the frequency response predicted by a reduced-order model satisfies the defined specifications. Once a sizable disturbance is detected, the pre-calculated signals are applied to the DERs. The proposed synthesis methodology is verified on the full nonlinear model in Simulink. A robust factor is imposed on the specifications to compensate the response mismatch between the reduce-order model and nonlinear model so that the nonlinear response satisfies the required TLS.

“…E NVIRONMENTAL, technical and economic issues have been increasing the penetration of renewable energy sources (RESs) in the power system [1]. The replacement of synchronous generators (SGs) with large scale RESs has a significant impact on the power system dynamics and plays a crucial role on the system stability [2]- [5]. The British National Grid recently reported undesirable trends including increasing voltage and frequency oscillations, declining frequency response, inertia, reactive power support and short circuit level, which have been associated with high RESs penetration [6], [7].…”

The low-frequency oscillations (LFOs) inherent in power systems will be impacted by the increasing penetration of renewable energy sources (RESs). This paper investigates the impact of virtual synchronous machine (VSM) based RESs on the LFOs in power systems. A detailed two-machine test-bed has been developed to analyze the LFOs which exists when VSMs replace synchronous generators. The characteristics of the LFO modes and the dominant states have been comprehensively analyzed. Furthermore, this study analyzes the LFO modes which exists in an all-VSM grid. The role of the power system stabilizers in the all-VSM grid has been comprehensively evaluated. The IEEE benchmark two-area four-machine system has been employed to corroborate the results of the small-signal analysis and observe the transient performance. The analysis in this paper have been performed in MATLAB/SIMULINK environment.
